So far, the analyses of the polarized structure functions of the proton and neutron have been limited to the evaluation of their integrals and comparing them to the prediction of the static-quark model of the nucleon. We extended our analysis to the x dependence of the polarized structure functions and observe that the measured structure function excellently agrees with the prediction of the static-quark model for Bjorken x > 0.2 and drops rapidly for x < 0.2. It is suggested that for Bjorken x > 0.2, electrons get scattered on the undamaged constituent quarks (alias valence quarks) denoted as quasi-elastic scattering on the constituent quarks and for x < 0.2, the constituent quarks fragment. In the fragmentation, strong interaction is involved which does not preserve the polarization.
